Description

Compound concrete-filled tubular column assembled docks node and connection method
Technical field
The present invention relates to the splicing structure structure in a kind of construction, it particularly relates to a kind of compound steel tube concrete Earth pillar assembled docking node and attaching method thereof.
Background technology
At present, China is in high speed urbanization and the stage of industrialization, from nineteen ninety-five Minstry of Housing and Urban-Rural Development of People Republic of China's issue《Building Industrializing implementation outline》, firmly the portion of building has set up " national housing industrialization base " in succession, " novel building industrializes integrated construction The bases such as Engineering Technical Research Centre ", it is intended to promote China's building industrialization process.As fully visible, greatly develop construction it is convenient, Prefabrication structure of good performance tallies with the national condition demand, to realizing that Industry Structure reform has important meaning Justice, while there is far reaching significance to accelerating China's architectural industrialization, industrialization.
Steel core concrete column has high capacity, rigidity big, anti-seismic performance and fire resistance is good and processing and fabricating simplicity etc. Advantage and be widely used in building structure.Compound concrete-filled tubular column is that steel pipe is added in concrete filled steel tube, is given full play to The characteristics of steel tube confinement performance is good, and then improve structural bearing capacity and rigidity, mitigates post and conducts oneself with dignity and improve its plasticity and toughness.
Splicing structure construction procedure of the existing compound concrete-filled tubular column in construction is generally:
(1) docking of interior steel pipe.Interior steel pipe outside weldings otic placode is fixed temporarily as steel pipe column, correction post perpendicularity with it is upper Lower floor's post flatness, is then connected upper strata post and lower floor's post by otic placode, then carries out interior steel pipe column by butt weld Connection.
(2) erection of steel reinforcement cage.
(3) docking of outer steel pipe.Outer steel pipe outside weldings otic placode is fixed temporarily as outer steel pipe column, and correction post is vertical Degree and flatness, then connect steel pipe column outside the upper and lower by otic placode, then carry out outer steel pipe column by butt weld Splicing.
(4) concreting is with vibrating.
This above-mentioned four steps of compound concrete-filled tubular column splicing are required to construct at the scene, and are related to substantial amounts of welding Operation, pour wet trade and positioning centering, perpendicularity correction etc. process.For a high building structure, traditional construction scheme A large amount of weld jobs are carried out in high-altitude mostly, high to workman's technical requirements and there is certain construction risk, therefore improve building Structural cost;Involved work post is more in construction, high to site operation site requirements, coordinates construction requirement between each work post high;Greatly The wet trade of amount not only can extend the duration, slow down structure construction progress, and live construction can not ensure steel pipe column interior concrete Perfusion effect;In addition, requirement of the live substantial amounts of wet trade to construction site, construction equipment is higher, it is necessary to substantial amounts of manpower money Source is managed coordination, increases building structure cost.
Therefore, it is badly in need of a kind of compound concrete-filled tubular column for being easy to manufacture, easy construction and assembled connection at present to splice Node, in order to which compound concrete filled steel tube system realizes that overall assembled is constructed, and then promotes such system in engineering Application.
The content of the invention
It is in view of the above-mentioned drawbacks of the prior art or not enough, it is an object of the present invention to provide a kind of compound steel pipe is mixed Solidifying earth pillar assembled splicing node and connection method, the connecting node uses full bolt connection, and reduces concrete work;Using The connection method of compound concrete-filled tubular column assembled splicing node can realize compound concrete filled steel tube overall assembled Connection, and easy construction, low cost.
In order to realize above-mentioned task, the present invention uses following technical solution:
A kind of compound concrete-filled tubular column assembled docks connecting node, it is characterised in that including first node joint, the Two node joints, the first channel-section steel joint, the second channel-section steel joint;Wherein, first, second described node joint is connected by two fronts Fishplate bar, two side gussets and connection panel composition, two front connecting plates and two side gussets pass through four connections Lath surround and is symmetrically welded the surrounding in interior steel pipe, and after the completion of welding, end at one end is respectively welded to connect panel, structure respectively Connecting node is docked into levels post.
According to the present invention, the second connecting hole is offered on described connection panel, for connecting the connection between panel, even The thickness of junction plate is more than or equal to 4mm.
Further, the width of described front connecting plate and side gussets is not less than 50mm, and length is not less than 100mm, thickness is not less than 4mm, and the width ratio connection panel narrow width of front connecting plate and side gussets is not less than 20mm.
Reserving hole is poured on described connection panel, and pours the aperture of reserving hole and is not less than 6mm, panel is connected It is concordant with interior steel tube end part.
Above-mentioned compound concrete-filled tubular column assembled docks the connection method of connecting node, carries out according to the following steps:
Step one:By the interior fastener for connection of first, second node joint and levels post;
Step 2:By first, second node joint further with outer fastener for connection, set up it is pre-buried pours pipe, and pour mixed Solidifying soil;
Step 3:By connecting the connection panel of first node joint and Section Point joint, upper strata and lower floor's post are completed Docking, and first, second node joint is wrapped up from both sides by the first channel-section steel joint and the second channel-section steel joint;
Step 4:Joint concrete or grouting material are poured by pouring preformed hole.
Compound concrete-filled tubular column assembled docking connecting node of the present invention and attaching method thereof, with prior art phase Than having the advantages that:
(1) compound concrete-filled tubular column assembled of the invention docking connecting node uses full bolt connection, can be effective Difficulty of construction and workload that the traditional butt weld connect band of reduction is come, and exempt the perpendicularity correction work of conventional post docking, Simple and quick construction.
(2) compound concrete-filled tubular column assembled of the invention docking connecting node can be prefabricated in the factory, and factory with Compound concrete filled steel tube connection, it is possible to achieve the overall assembled connection of compound concrete-filled tubular column structure, scene is only docked Bolt connection and channel-section steel track bolt connection two procedures, easy construction.
(3) compound concrete-filled tubular column assembled of the invention docking connecting node is by way of reserved pouring hole, letter Change and process is poured after the concrete of joint, improve the efficiency of construction of post docking connection.
